a) teorema inaltimii
[tex] MQ^{2} [/tex]=NQxQP=4x9=36
MQ=rad36=6
b)teorema catetei
NP=NQ+QP=2+9=11
[tex] MN^{2} [/tex]=NPxNQ=2x11=22
MN=rad22
c)PN=PQ+Qn=4+5=9
teorema catete
[tex]MP^{2} [/tex]=PNxPQ=4x9=36
MP=rad36=6
d)teorema Pitagora
[tex]NP^{2} = MN^{2} + MP^{2} [/tex]
[tex]NP^{2} = 400+225=625
NP=rad625=25
